摘要：

The 4f3 configuration of Nd3+ in NdF3 has been revisited. The real point symmetry of the crystalline matrix-C3-been considered for the simulation, which means 15 crystal field parameters (CFPS). The simulation has been conducted by considering together the energy level scheme derived from the optical absorption spectra and the paramagnetic susceptibility and its variation with the temperature and the g values of the ground level. It is shown that only a single set of CFPS reproduces this information correctly, whereas various sets are found if only the energy level scheme is retained in the simulation process.
